At the commencement of the distillation the product flowing into x will not be pure alcohol, andthe proof will be below the above standard, the stop-cock on the left of the separator q a: will be opened, and the low wines be conveyed back through pipe I as into the lowwine tub; but when the hydrometer indicates the proper degree of proof, this communication is closed, and the alcohol conveyed as above described, by opening the stop-cock to the right of the aforesaid separator.

The low-wine tub L is an inclosed vessel receiving all the low wines resulting from this double distillation. These low wines are from time to time conducted through pipe I d, by opening a stop-cock into D the doubler, in which the alcoholic principles there- 'of will be revaporized and converted into alcohol, as

hereinbefore described.

After continuous operations, .a residuum of water and impurities will collect in the boiler A, after the alcohol has been distilled therefrom, and which must cock at.

This stop-cock n is seldom opened, and to guard the entire closure of the whole apparatus, it is fastenedby a lock, the key being in the hands of a trusted person.

What I claim, and desire to secure by Letters Patent of the United States, is-

The still S, pipe s d, doubler D, pipe (I w, and the worm-pipe and tub WV, in combination with pipe at u, low-wine tub L, pipes l d and h 71, alcohol column 0, the charger H, pipe 0 -v, goose-tub V, pipes 11 a: and c" c, the worm-tub X, pipes h x, and l a: and h a, boiler A, and pipe d c, discharge-pipe and stop-cock 'n, for manufacturing alcohol from mash or wort, 850., in the still S by one continuous operation, substantially as and for the pulposeset forth, with or without the separators g '10 and q Witnesses: LUDVVIG WOLFF.
